Selecting a Block of Text, rather than a Windows selection

[aao]

Hi, I am new on this forum. Just got the terminal emulator installed today. Previously we used Anita, but it is not apparently secure enough for our DBA.

I am interested to know if there is a way to configure the "click and drag" functionality to effectively SELECT (Microsoft word) a rectangular block of text, rather than the conventional way that Word does it. I ask this because in many cases, I would like to eliminate the line numbers on the far left when I am copying code.

Any help is appreciated. TIA.
